短信接口源码，实现按钮变灰，倒计时的功能，非常不错
不多说费话了，直接上代码，有什么不懂的朋友可以给我留言，关于代码中返回值代表多少请参考官网，短信接口：http://www.56dxw.com 关于js的下载可以百度搜索一下，关于图片验证码可以从网上找一下，在这儿只记录一下如何调用短信接口实现短信的发送的

说明：<br />
1.以下验证码例子采用的是先获取手机号文字验证码，如果文字验证码收不到，将采用语音播放验证码的形式，两种形式的结合，基本避免个别手机号收不到的问题，从而是验证码的成功率接近100%，有效的避免客户的流失。<br />
2.文字短信验证码和语音短信验证码只是修改一下调用接口的文件名称即可，需要注意的是语音验证码内容是4或6位的数字。<br />
3.以上只是一个简单的调用的例子，关于返回值可参考官网<br />
4.以上先加上图片验证码，然后才可以获取手机验证码，主要是为了防止有些软件恶意获取手机号给它人发送，从而造成短信的浪费，当然方法有很多。不一定非要这一种，这种方法也可能不能完全避免软件恶意获取，但相对还是有效的。
